TO ALL WHOM IT MAY CONOERN:

Be it known that I, 13. W. COLLIER, of Oxford, in the county ofLafayette, and State of Mississippi, have invented a new and improvedHand-Sewing Machine; and I do hereby decla-re the following to be afull,clear, .and exact description of the nature, construction, and operationofv the same,- reference beingihad to the accompanying drawing, which ismade a part of thisspecication, and represents a perspective view of' myimproved hand-sewing machine, the working surface or table beingindicated in red outline, so as not to conceal the enclosedoperatingmechanism.

'lhe nature of my invention consists in the arrangement of a bobbin'andlooping-hook Within a case or box attached to one of a pair of levers orhandles pivoted together and formed with finger-loops like thetwo partsof a pair oi' shears, the needle being attached to the corresponding endof the other lever-.and operated-V hy opening and closing the instrumentby hund. The instrument is adapted to be carried about from place toplace, and may be supported by the hand without serious inconveniencewhen in operation.

In order that others skilled in the art to which my invention appertainsiii-.ty be enabled to fully understand and use the same, I will proceedto describe it in detail.

A A are a pair of levers pivoted together at a, and formed-at one endwith loops B B, to enable them to be operated by the thumb and fingerafter the manner of shears. At their opposite ends these levers areprovided with the ease or box O and the horizontal arm D. E is a looper,suitably' journalled within the-case C, and F is a hobbin arrangedwithin the looper E. G (red lines) is the top oi' case G, upon whichrests the matcrial to be sewed. H is the needle, adjustably secured tothe end of the arm D, and occupying suoli position in relation to lthemechanism E E F that when the levers are closed the needlel passesthrough its hole in the top G o? the case C, within which it leaves aloop to be caught by the hook and carried around the bobbin. I is thespool which holds the thread for the needle, said spool beingniountezl'upon the lever A. The latter also supports the spring-tensionpulley K, around which the thread extends from the spool to the needle.Ii is a pinion, iixed upon the shaft or axis of the looper E, andengaging with the seinicircnlar cog M, which 4is enclosed within theframe O, and `actu-ated by a rod, N, attached to the end ot lever A.When the llevers A A are closed the cog M is, by the action of the'rodN, made to rotate the looper E in one direction through the medium ofthe pinion L. The looper is rotated in an opposite direction, the needleis raised, and the levers opened, as often as the said levers are closedby hand, by the elasticity of the spring O. 'Ihe looper E is made topetorin a complete revolution in both directions,- that is to say, ithas a reci'rocating motion upon its axis instead of a continuous rotarymotion like the looper in the llVheeler and Wilson sewing machine; yetthe looper,bobbin,.and make of stitch are analogous to those of themachine cited. .The downward motion of the needle-carrier D puts theneedle through the cloth and turns the hook E backward in position tocatch the loop of the needle-thread, and the upward motion causes thehook to take hold of the loop and pass it Aentirely around the bobbin,when the iloop becomes disengaged and the motion of the looper isreversed.

No feeding device is shown, as it is the intentiony to employ such as isused in the Wheeler and Wilson machine, or any other that may belconveniently applied. I

Ilnving thus describedl my invention, the following is what I claim asnew herein, and desire to secure by Letters Patent: i

I claim the combination of thelevcrs A A, B Il, ease O, arm I), needleII, rotary' looper E, hook E", b'obbin F, pinion Il, cog M, rod N,spring O, and spool I, all arranged as herein described for the piirposespecified.
